论文摘要
人们越来越担心的是，大型冠状质量弹出事件将引起对光纤跨科电缆的电源的扰动，该电缆可能会产生全球互联网停电。在本文中，我们给出了电压变化的表达，即地磁场的瞬时变化会导致跨波动光纤电缆的电源电源的电压。我们表明，瞬态电压变化与磁场偏差的幅度成正比，而不是其时间导数，因为法拉第定律的直接应用将暗示，这暗示着设计标准以保护跨科学光纤系统针对大型地磁风暴事件。提出的分析还可以将现有系统分类为某些人对强烈的地磁风暴中发生的地磁场的弱敏感，而当发生地磁场的弱化时，这些系统会更容易经历中断。
There is a growing concern that a big coronal mass ejection event will induce perturbations on the power supply of fiber optic transoceanic cables that may produce a global internet blackout. In this paper we give the expression of the voltage variations that a transient change of the geomagnetic field induces on the voltage of the power supply of a transoceanic fiber optic cable. We show that the transient voltage change is proportional to the magnitude of the magnetic field deviations and not to its time derivative as a direct application of Faraday's law would imply, and this suggests design criteria to protect transoceanic fiber optic systems against big geomagnetic storm events. The presented analysis also enables the classification of existing systems into some that are less sensitive to the weakening of the geomagnetic field occurring during strong geomagnetic storms and others that are more prone to experience an outage when a weakening of the geomagnetic field occurs.
